MG51LD1AE

NuMicro® MG51LD1AE is an embedded Flash Memory type 1T 8051-based microcontroller. The instruction set is fully compatible with the standard 80C51 and performance enhanced. It supports 16 / 24 MHz core speed and features up to 64 KB of Flash Memory, 256 bytes of RAM and 4 KB of auxiliary RAM (XRAM), 4 KB of Flash loader memory (LDROM), 2.4V to 5.5V operating voltage, and -40°C to +105°C operating temperature.

The MG51 series also provides plenty of peripherals including four 16-bit Timers, two UARTs with frame error detection and automatic address recognition, three ISO 7816-3 interfaces, one SPI, one I2C, six basic PWM output channels, six enhanced PWM output channels, and 15-channel 12-bit 500 ksps ADC with continuous mode.

For the development, Nuvoton provides the NuMaker evaluation board and Nuvoton Nu-Link debugger. The 3rd Party IDE such as Keil C51, IAR EW8051, and NuEclipse SDCC compilers are also supported.
